Latest Patents
One of Barbosa's latest patents is titled "Integrated micro-lens waveguide and methods of making and using same." This invention features a probe structure that includes a monolithically integrated waveguide and lens. The probe utilizes SU-8 as a guiding material. The waveguide mold is defined through wet etching of silicon, employing a silicon dioxide mask patterned at a 45° angle relative to the silicon substrate edge. An aluminum layer is deposited on the silicon substrate to act as a mirror. Additionally, a lens mold is created using isotropic etching of a fused silica substrate, which is then aligned to the silicon substrate. A waveguide polymer, such as SU-8 2025, is flowed into the combined waveguide mask and lens mold by reducing its viscosity and utilizing capillary forces through careful temperature control of the substrate.
